Fly-in, fly-out workers have been urged to check the status of their measles jab after three cases were linked to a Pilbara mine site.

WA Health released the public health warning on Thursday after the latest cases reported to the department this week related to a Qantas flight from Christmas Creek Mine to Perth.

The flight departed the mine site just before midday last Thursday and arrived in Perth just after 1.30pm with an infectious passenger aboard.

The person then spent several hours at the Virgin Australia lounge in Terminal 1 at Perth Airport.

The Fortescue-operated Christmas Creek Mine, about 145km north of Newman, was on Friday declared an exposure site over several days, from September 8-11 inclusive.
